The calendar refers to the year, month, day and hour expressed by heavenly stems and earthly branches combination.
Time is always represented by trunks and branches. Ten-day trunks and twelve-day branches are matched in turn, which is exactly the cycle of sixty groups, namely:
Birthday consists of four pillars, namely, year, month, day and hour, each with two words, a total of eight words, commonly known as "four pillars and eight characters".
The black box is a birthday, and the red box is a birthday.
How to calculate "eight characters"?
year
We often talk about "sixty flowers and sixty flowers", and cadres and branches keep records for sixty years. For example, 2022 this year is the year of 1898; Last year, 2022 was Ding Younian; Next year, 2022 is the year of the ocean; And 1958 60 years ago was also the year of the 1898 Movement.
moon
The month is based on the Xia calendar, and the summer calendar is "the first month is cloudy", that is to say, from the first month of the lunar calendar to the twelfth month, it is expressed in turn as: silver moon, Uzuki, Chen Yue, Mitsuki, noon, unfinished, Shen Yue, moon, month, month and ugly month.
In this way, we can easily get the monthly branch, so how to calculate the dry days of the month? The monthly dryness can be calculated from the annual dryness, as shown in the following table.
Of course, there are secrets. The ancients handed down a set of secrets to calculate the dry branches of a month by the dry days of the year, which is called "Five Tigers Dodging Yuan".
In the first year, C was the first.
B Geng is old, and E is the head.
Bing Xin will definitely find Geng,
Ding is downstream.
If you ask Wu Gui where to send it,
Good news is good at pursuing.
For example, 2022 is 1898, and the annual dry day is "E", so today is March 30, 2022 (February 14 of the lunar calendar), and the monthly dry day is "B", which is the first month.

Since February, the third year of Lu Yingong (722 BC), the 60th anniversary of the division of China has never stopped, and it is also the longest known calendar in the world.
Calculating the dates of trunks and branches is complicated, but there is also a shortcut, that is, finding a perpetual calendar.
For example, March 30, 2022 (February 14 of the lunar calendar) is a sunny day.
Some people ask blind people to tell their fortune. Why can't we launch horoscopes without consulting the perpetual calendar? That's because the formula for calculating the date of expenditure is complicated and is not recommended. I can use mathematical equations to show you:
Heavenly dryness formula: g = 4c+[c/4]+5y+[y/4]+[3 (m+1)/5]+d-3.
The remainder of g divided by 10 is the corresponding heavenly stems.
Ground support formula: z = 4c+g+10+i.
The remainder of z divided by 12 branches accordingly.
Description of the formula: where c represents the first two digits of the four-digit calendar year, y represents the last two digits of the four-digit calendar year, m represents the calendar month and d represents the calendar days.
Note: If the month is 1 or 2, it is calculated according to the previous year's 65438+March and 65438+April.
Odd months i=0 and even months i=6. When calculating, the number with [] indicates rounding (rounding the remainder, such as 3.8, take 3).
For example: Gregorian calendar1October 24th 1964 65438+9: 00.
g = 4C+[C/4]+5y+[y/4]+[3(M+ 1)/5]+d-3 = 4(20- 1)+[ 19/4]+564+[64/4]+[3( 10+ 1)/5]+24-3 = 443
443, except 10: 3
z = 4C+G+ 10+I = 4 19+443+ 10+6 = 535
535, except 12: 7
So the date is: bingwu day.
It's complicated, right? So honestly check the perpetual calendar.
time
At the moment the earthly branch is:
Hours: 23: 00- 0: 59 am
Ugly time: 1 pm-2: 59 am
Yin Shi: 3 am to 4: 59 am.
Shi Mao: From 5 am to 6: 59 am.
Morning: 7: 00 a.m. to 8: 59 a.m.
Shi Si: 9: 00- 10: 59.
Noon: 1 1 p.m. 12: 59
Not yet:-14: 59 pm
Application time: 15 pm-16: 59 pm
Unified time: p.m. 17- 18: 59
Time: 19- 20: 59 pm
Shihai: 2 1 pm-22: 59 pm
Divide the date around midnight, and a new day will be after 23: 00.
When the weather is dry, it can be calculated by the monthly weather. See the table below for details:
A also added a, b heptyl c was the first one.
Bing Xin starts from E and lives in Geng Zi.
When you are young, you start looking again and again.
For example, on March 30th, 2022, the drought was "Xin", so today's 12 (noon) drought was "A", that is, "Wu Jia time".
Finally, I will give you three birthdays. You can try to push the birthdays of these three people, and the answers will be announced in the comment area.
Gregorian calendar of birth:1May 23, 986 at 8: 37 (time)
Gregorian calendar of birth:1September 9591June 4 19: 37 (time)
Gregorian calendar of birth:1September, 992 16: 37 (time
The above is the case of Xin Youri's eight characters 100, and the sharing of ten days' work and twelve branches. After reading the life with a bright heart, it is very bitter. I hope this will help everyone!
